Area loosely approximating everything north from Newcastle Waters in the south, then heading south west to the Birrindudu area on the NT/WA border and again from Newcastle Waters heading east to an area approximating Mount Drummond area on the NT/QLD border.
In this zone, which includes tick, Three-Day and buffalo fly, combined with heat, humidity and very heavy monsoonal rainfall, there are greater challenges for Angus bulls, however, they can still be used effectively.
Careful management including acclimatization, parasite treatments, seasonal mating and reduced handling during warmer weather is strongly recommended. Allowances for extra mustering time and pushing the mob may also be a consideration for Angus influenced mobs. Almost entirely used in cross-breeding programs and stabilized composites.
Area loosely approximating from Newcastle Waters in the north, heading east to an area approximating Mount Drummond on the QLD/NT border, down to the Georgina Downs and Lake Nash areas, before heading west to the NT/WA border, back up to approximately Birrindudu and then north east back to Newcastle Waters.
Characterised through very warm to hot conditions with rising humidity. Includes known buffalo fly and three-day sickness zones. Angus bulls and females under reasonable management regimes exhibit productivity and longevity. Cross breeding using Angus genetics is also common within this zone.
Area loosely approximating from the Georgina Downs and Lake Nash area on the QLD/NT border down to Tobermorey area, whilst skirting the Simpson desert from approximately Indiana heading a south-south west direction until the NT/SA border. From here, head west to an area approximating Mulga Park, before heading north north east to an area just north of Papunya and then heading north west to an area just west of Chilla Well and then due west until the NT/WA border.
Typically, hot and dry with low annual rainfall. Angus bulls and females can perform well when managed appropriately through allowances with nutrition and breeder herd management and perform equally as well in cross breeding programs.
